Hello, thanks ahead of time for those of you trying to help me. I have a C++ assignment that I have basically done, but there are some tweaks I can't figure out. I have to write a program that generates a series of random numbers and stores them into a C-style array. My teacher made us use a 'bool' function for this, but I've figured that part out. I'm trying to figure out how to use a printData function to [1] print the data to the screen, and [2]print the data to a file called "randomArray.txt".
Here's my function so far:
void printValues(ostream& fout)
{
if(!randomArray(variance, mean, numPoints, x))
{
fout<<randomArray(variance, mean, numPoints, x)<<endl;
fout<<"\n"<<endl;
}
}
NOTE: It also says that my "ostream& fout" object was not declared or can't be used this way etc.

Ok. It's very hard to help you without the full code or the interfaces (at least), because (1) we don't know what randomArray() does (does it return a pointer), (2) I see no reference to an array in your function (is it global?). Here's something that may or may not help you.
////////////////
#include <iostream>
#include <cmath>
#include <fstream>
#include <cstdlib>
#include <ctime>
using namespace std;
int* getrandomlist(int);
void print(ostream&, int*, int);
int main()
{
int size = 5;
int* list = getrandomlist(size);
print(cout, list, size); //console
fstream fout("data.dat");
print(fout, list, size);//file
fout.close();
free(list);
}
int* getrandomlist(int size)
{
int* buf = (int*)malloc(sizeof(int)*size);
srand(time(NULL));
for(int i = 0; i < size; i++)
{
buf[i] = rand() % 10 + 1; //between 1-10
}
return buf;
}
void print(ostream& out, int* list, int size)
{
for(int i = 0; i < size; i++)
{
out << list[i] << endl;
}
}
